"the patient's feet will be at the end of the table and often if not careful; the skyline projection may also be a heavily magnified projection of the distal phalanges; ensure the patient's feet are plantar-flexed/out of the primary beam"

"it is possible to use a detector stand rather than asking the patient to hold the detector; this alleviates the risk of motion artifact"
